Chrysanthemum plant named ‘Yogigi Gold’

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Yogigi Gold’, characterized by its compact, upright, outwardly spreading and rounded plant habit; freely branching habit; dense and full plant habit; uniform and freely flowering habit; decorative-type inflorescences with obovate-shaped ray florets; golden yellow-colored ray florets; and natural season flowering about September 26 th  in the Northern Hemisphere.

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Yogigi Gold’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially grown as a garden Chrysanthemum and hereinafter referred to by the name ‘Yogigi Gold’.

The new Chrysanthemum is a naturally-occurring whole plant mutation of the Chrysanthemum×morifolium cultivar Yogigi, not patented. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant from within a population of plants of the cultivar Yogigi in a controlled environment in Alva, Fla. in May, 2005.

Asexual reproduction of the new Chrysanthemum by vegetative cuttings was first conducted in Alva, Fla. in July, 2005. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Yogigi Gold have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yogigi Gold’. These characteristics in combination distinguish ‘Yogigi Gold’ as a new and distinct garden Chrysanthemum cultivar:

-   -   1. Compact, upright, outwardly spreading and rounded plant         habit.     -   2. Freely branching habit; dense and full plant habit.     -   3. Uniform and freely flowering habit.     -   4. Decorative-type inflorescences with obovate-shaped ray         florets.     -   5. Golden yellow-colored ray florets.     -   6. Natural season flowering about September 26^(th) in the         Northern Hemisphere.

In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the parent, the cultivar Yogigi, in the following characteristics:

-   -   1. Plants of the new Chrysanthemum flower earlier than plants of         the cultivar Yogigi.     -   2. Plants of the new Chrysanthemum and the cultivar Yogigi         differ in ray floret color as plants of the cultivar Yogigi have         light pink-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Golden Yolynn, disclosed in U.S. Plant Pat. No. 14,721. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Golden Yolynn in the following characteristics:

-   -   1. Plants of the new Chrysanthemum were smaller and more rounded         than plants of the cultivar Golden Yolynn.     -   2. Plants of the new Chrysanthemum were more flexible and less         brittle than plants of the cultivar Golden Yolynn.     -   3. Plants of the new Chrysanthemum had smaller inflorescences         than plants of the cultivar Golden Yolynn.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Chrysanthemum. The photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum.

The photograph at the top of the sheet is a close-up view of typical inflorescences of ‘Yogigi Gold’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Alva, Fla. during the late spring and early summer in a polycarbonate-covered greenhouse and under conditions and practices which approximate those generally used in commercial garden Chrysanthemum production. During the production of the plants, day temperatures averaged 32° C. and night temperatures averaged 21° C. Plants were grown in containers, exposed to long day/short night conditions and pinched one time. One week after the pinch, the photoinductive short day/long night treatments were started. Plants used in the photographs and for the description were about three months old. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
